How can we improve InDesign?

Allow us to create PDF (or postscript file) for thumbnails.

Currently InDesign will not let me create a PDF of thumbnails for a document. This would be valuable because I could then send a compact PDF file to a colleague for layout review, before sending the full PDF.

Alternatively, allow the creation of a PostScript file. Right now, if I try do do it in the printer menu, it disables the thumbnails options; if I try to use it via the Printer… button, it seems to work — even asking me to pick the filename — but does not create the PS file.

This is an idea that should have been implemented long ago. We can print thumbnails, but cannot export a pdf with thumbnails? Why is the same thumbnail / multiple pages per sheet not supported for export?
